JSON.parse: unterminated string at line 1 column 17275835 of the JSON data JSON.parse: unterminated string at line 1 column 17275835 of the JSON data
This indicates to me that the JSON is not fully written to disk yet. If this was a network issue, the column number at which this fails would be different for all five attempts, but it's the same, so my browser gets the same exact response every time.
search index: found cached version 76S9MGFNGAVCEA0M not matching target GPQGME7P71IV1540
This might indicate a good solution to this issue: Only update the search index version once you've confirmed that it was fully written to disk and that the API also returns a version that can be successfully parsed. If not, leave the index in the previous, known-good state.
